METHOD OF MOUNTING LATHING STRUCTURES FOR PLASTER WALLQ.

Application filed October 26, 1926. Serial No. 144,235.

This invention relates to improvements in. the art of plaster wallconstruction, particularly of that type shown in my issued Patent No.1,579,377, dated April 6th, 1926, and the present application relates tocertain improvements upon and extens ons of the method and structureshown in said patent.

In the wall structure to which this invention relates small channel ironstuds about three-fourths of an inch wide by three eighths of an inchthick are inserted between the floor and ceiling of a building and-SLlli'- ably anchored. Plaster lath, preferably of the type shown inthe above identified patent, is then laid across the face of the studsand initially secured thereto in the manner described in said patent.The preferred average width of the plaster lath strips used is fromtwelve to eighteen inches. In some municipal jurisdictions, however,ordinances are in force which require that plaster lath of the type usedby me must be secured to the stud at points less than twelve to eighteeninches apart, usually about six inches apart. Inasmuch as the specificstructure as carried out in accordance with the above identified patentprovides merely for fastening the lath strips to the studs and to eachother at the horizontal edges of the studs, it therefore becomesnecessary that in addition to the fastening means described in saidpatent some intermediate fastening means be provided, and therefore Ihave designed and perfected the method and structure which is thesubject matter of this present application.

In the drawings:

Fig. 1 is a perspective View of a fragmentary portion of awall in whichthe plaster lath strips have been secured to the stud and to each otherin the manner and form set forth in the above described patent, andshowing the tool used in the present method positioned as it would beready to puncture the lath adjacent the stud for the purpose ofinserting the additional securing elements.

Fig. 2 is a similar view to that shown in Fig. 1 showing the conditionof the lath immediately after it has been punctured by the tool shown inFig. 1.

Fig. 3 is a sectional view taken on a line 3-3 of Fig. 2.

Fig. 4 is a perspective View of a small protective metal strip used inconjunction with my improved method.

Fig; 5 is a plan View of a fastening wire. Fig. 6 1s a plan view of thetool used in carrying out my present method, with a portion of thehandle broken off.

Referring now more particularly to the characters of reference on thedrawings, the numeral 1 designates the stud and the numeral 2 theplaster lath strips laid across the face of the stud, and secured to thestud and to each other by clips 3 and 4 respectively, mounted andarranged as specifically described in said patent.

In carrying out my improved method I first provide a tool comprising ahandle 5 carrying a flat cutting member 6 at its work end, such cuttingmember being provided with two spaced and sharp corners 7, back of whicha slot 8 is cut into the front edge of the tool. This slot 8 is of aslightly greater width than the thickness of the stud 1. After theplaster lath strips 2 have been mounted to the stud in the manner shownin Fig. 1, the too-l is positioned against the lath at apointintermediate the clips 3 and with the points 7 positioned so thatthe slot 8 will be lined up on opposite sides of the stud 1. The tool isthen struck a blow with the hand or other instrument, which drives thepoints 7 through the plaster lath on each side of the stud 1, formingslots 9.

Protective plates or strips 10 are provided with small prongs 11 andafter the slots 9 have been formed one of these protective strips 10 isplaced on the face of the plaster lath strip longitudinally of the stud1 and intermediate each pair of slots 9, the prong 11 being pressed intothe plaster lath to hold the strip in position while the operator isplacing the fastener around the same.

A fastening wire 12 is then projected through the slots 9 to straddlethe protective strip and the strip of the plaster lath between the slotsand the stud. Said wire is then twisted together in this position and,as is obvious, will form a very excellent fastening means for theplaster lath strip to the stud intermediate the clips 3. The

protective strips 10 prevent the wire fas-' tener 12 from cutting intothe soft plaster lat-h strips, which would render the fastenlngineffectual.

Having thus described my invention what mediate their edges, the slotsof each pair being disposed on. opposite sides of a: stud,.

and positioning fastening elements through the slots and around thestuds and plaster lath strips between each pair of slots.

2. The method 01 erecting a lathing structure for plaster lath Wallscomprising. setting the studs, laying plaster lath strips across thefaces of the studs and securing them to the studs at the edges of the1am, forming slots in pairs in the face of the lath strips intermediatetheir edges, with the slots of each pair disposed on opposite sides of astud, and positioning fastening elements through the slots and" aroundthe studs and plaster lath strips hetwen each pair of'slots.

3. The method of erecting a lathing structure for plaster lath wallsconiprising setting the studs, laying plaster lat'h strips against thefaces of the studs, formingslo'ts in pairs in the faces of the stripsintermediate their edges, the slots of each pair being disposed onopposite sides of a stud, positioning fastening elements through. theslots and around the studs and plasten lath strips between each pair. ofslots, and placing protective elements between the fasten ing elementsandthe lath strips.

4. plaster lath structure comprising studs, plaster lath strips laidacross the faces of the studs; and provided? with pairs of slots intheir faces, the slots of a pair disposed on opposite sides of a stud,and a fastening element projecting througheach pair of slots and arounda stud and lath strip.

5. A plaster lath structure comprising studs, plaster lath strips laidacross the faces of the studs and provided with pairs of slots in theirfaces,,the slots of a pair disposed on opposite sides of a stud, atastening element projecting through each pair of slots and around astud and lath strip, and protective elements secured between thefastening elements and lath strips.

6; The method of'erecting a lathihg structure for plaster wallscomprising setting the studs, laying a. plaster lath strip across thefaces of the studs and securing it to the studs, then piercing the lathbetween its edges and adjacent thestuds,and thenp'tositioningtz'istening' elementstl'irough' the holes in the lath and around thestuds. 7

7 The methodoiterecting a lathingstru'cture for plaster lath wallscomprising setting the studs, laying a plaster. lath strip" across thefaces ofthe studs, forming slots in the strip adjacent the studs andassoc-iating fastening elements with the stud and lath and through theslots to secure the lath to the studs.

In testimony whereof I my signature.
